Hello Simon

Check the event viewer for a robot serial number mismatch message, 
I think it is in the application view. 

Also make sure that you have the SSO license on all media servers.

What version of NBU are you running ?

Regards
Michael

> For example, after moving drives or PCI cards around in media servers you 
will need to go through this process to ensure all the paths match, between 
the OS, robotic tools and Net Backup :
* Do the necessary to get the OS up to date, i.e. remove /dev/rmt entries and 
reconfigure reboot. 
* Check how many drives can be seen using sgscan tape. Depending, it may not 
be necessary to reinstall the sg driver. 
* Re-install the (Veritas) sg driver. 
>
* rem_drv sg 
* rm /kernel/drv/sg.conf 
* /usr/openv/volmgr/bin/driver/sg.install 
* Check all drives can now be seen using sgscan tape. 
>

* On each media server, delete all drive definitions from the Media Manager. 
>
* List Net Backup drive numbers using tpconfig -d 
* Delete each using tpconfig -delete -drive {n} e.g. tpconfig -delete -drive 
0.

* ON each media server, delete all robot definitions from the Media Manager.

* List Net Backup robot numbers using tpconfig -d 
* Delete each using tpconfig -delete -robot {n} e.g. tpconfig -delete -robot 
0. 0 for gorilla, baboon, 1 for lemur, gibbon, grivet. 
>

* At this point vmglob -listall -java on any media server should return 
nothing, indicating that the Global Device Database has been synchronised 
after everything has been deleted. If not, try to delete remaining entries 
manually using vmglob -delete -drive -name <DriveName>, etc. - from the 
master server. 
* Get Net Backup to scan for all attached devices using tpautoconf -a. Or use 
the GUI "Configure Storage Devices" wizard. 
* At this point tpconfig -d will show all devices with default names e.g. 
DLT70001. 
* stopltid 
* ltid -v 
* Use the tpreq command to test mount as many tapes as possible, then 
tpunmount to unmount them.

> After now removing all storage units for my old media servers that were 
totally destroyed, I have installed NBU on the newly named media servers and 
attempted to run the device configuration utility from my Master.
> I have attempted to scan both new hosts but each one comes up with the 
following message....
> The error message reported is "Could not get device configuration. Cannot 
discover devices. see the troubleshooting guide for details (44)." I received 
an OK box.
> When clicking this, the Device Configuration Wizard asks "Device discovery 
failed on host Server001 do you wish to proceed - I say NO. Saying YES brings 
up the 1st message and the device configuration fails to continue as it 
cannot see the robot.
> This occurs whether I scan a single host, multiple hosts or ALL 3 hosts 
(Master as well).
> Under Media & Device Management, Devices, Robots and hosts I can see 
entries for SERVER001 and 002 - I wonder if someone has tried to configure 
the devices, and its failed somewhere along the lines and now NetBackup 
cannot understand what is happening?
> Currently doing a backup of my SAN devices over LAN for now.....
